i uiten STA TES EDWARD F. DUDLEY, OF OAK PARK, ILLICIS,` ASSIGNOR TO MEHLE PRINTING PRESS t MANUFACTURING CUMPANY, 0F

ILLINOIS.

` To all wlw/nt t may concern.'

Be it known that I, EDWARD F. DUDLEY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of lllinois, have invented certain new'and useful Improvements in ChaseMoun'tings, of which the following is a specification.

This invention relates to printing presses and more particularly to a chase mounting therefor'. Y Y

@ne object of the invention is to provide simple, reliable and efficient means for raising, lowering and angling the cha-seframe. Another object is to provide an improved mounting for a chase frame in which all the parts are accessible and cooperate in a manner to meet the various requirements for successful commercial use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, ini which- Figure 1 is a fragmentary elevational View of parts of the printing press embodying my invention;

Figure 2 is a sectional view taken in the plane of line 2-2 of Figure 1; and

Figure 3 is a sectional view taken in the plane of line 3-3 of Figure 1.y

The various novel features of the invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that I have disclosed my invention in connection withV a printing press having way-frame members in which the type bed 11 is mounted for reciprocation. Secured to the type bed 10 is an inking plate. 12, which lies below the chase frame 13 in which theplate or type, not shown, is mounted.

This invention has to do primarily with the chase mounting. When a chase is set in cooperative position with the type bed it may be found to be too low or too high, or it maybe found to be slightly out of `vertical alignment. Accordingly, it is desirable to provide some simple and reliable means for adjusting the position ofthe chase. To this end I have provided means which, in this embodiment of the invention, includes two jack studs 14 which are threaded into suitable threaded portions 15 of pockets 9 in the upper portion of the ink- CHICAGO, ILLIINOIS, 1Ar *CORPORATION 0F CHASE MoUn'rrNG.

Application filed 'April 22, 1922. sel-mnd. 555,954,

ing plate 12 near theopposite sides thereof. lt is the lower end 16 of each stud 14 which is threaded and directly thereabove is ay angle of degrees from the vertical. Thev chase is mounted Vand rests upon the coneshaped heads 19 of the oppositely arranged studs 14, and the inclined surfaces of the cone-shaped heads and of the beveled face 21 of the chase are made to extend at an angle with respect to each other to facilitate placing the chase in position andremoving same therefrom. After the chase is placed on top of the studs or jacks 14, a clamp 22 is placed in locking position over the upper cross member 23 of the chase for locking the chase in position. The locking member 22 is pivotally mounted on a stud 24 secured to the type bed 11 and is yieldably held in locking position by a. coiled spring 25 surrounding a rod 26, one end of which is pivotally connected to the locking member 22 and the other end of which is guidedly received in an opening 27 in the bed 11. It is seen, therefore, that the locking member 22, when in chase locking position, will permit an adjustment of the chase. is too high the jac screws or studs 14 may be lowered, whereupon the chase will follow as a result of fits own weight and asl a result ofthe tensionin the spring 25. If the chase is too low it maybe raised by raising the jack studs 14. 1f one side is Above' thisV 1f the chase.

too high or too low thatside'may be lowered or raised by adjusting the associated jackstud 14. For rotating or adjusting the jack studs 14 any suitable `pin may be used which may be inserted inthe tool or wrench openings 28.l

By means of this arrangement the chase may be raised, lowered or angled even while locked to the bed in a simple manner and,

vat the same time, the chase may be quickly and easily applied to and withdrawn from the type bed.

It is my intention to cover all modifica-- a. support, a chase, a jack stud adjustably s mounted in said support and on which said chase is mounted whereby the latter may be adjusted, and means for yieldably lock-V ing said chase whereby the latter may be adjusted While it is locked. v

2. In a printing press, the combinationof a support, a chase having its lowerportion beveled, a member associated with said chase .and adjustable with respect to said support and having apportion inclined at a di'ii'erent angle With respect to said bevel for facilitating the application and withdrawal of said chase.

3. In a printing press, the combination Vof a support, a chase, and a studadjustable in'saidsupport and on which said chase is niountedwhereby the latter may have its position adjusted, said chase and stud having engaging portions inclined at a different angle for facilitating application and Withdrawal of Lsaid chase with respect to the press.

4. In a printing press, the combination of a support, a chase Yhaving a portion thereof beveled, and a jack stud adjustable in said support and having a conical head on Which said chase is mounted for adjustment, the angle of said beveled portion and said conical head differing for facilitating application and Withdrawal of said chase.

5. In a printing press, thc combination of'a support, a chase having a portion thereof' beveled, a jack stud adjustable in said support and having a. conical head on which said Vchase is mounted for adjustment, the angle of said beveled portion and said conical head differing for facilitating application and Withdrawal of said chase, and a spring pressed lockingmember for yieldably forcing the chase against said jack stud and capable of yielding in accordance with adjustments of said chase.
